"Rip seaside boardwalk. So many of our favorite places gone..." tweeted Nicole "Snooki" Polizzi. "My heart is with everyone affected. Xoxo Beachcomber." Beachcomber Bar & Grille was a restaurant where the cast of the reality series spent their free time.

Below, other cast members weighed in on the disaster that officials say is 95 percent contained. However, investigators are suspicious of the fire's origins. "Fire of this magnitude with no obvious cause goes to the lead investigative agency in the county, which in this case is the Ocean County Prosecutor's office," one official told ABC News.
